Quartz, Japan Law Twin

The fine druse, likely a metallic oxide like manganese oxide, highlights the face of the Japan Law Twin (flattened, twinned quartz crystal) and provides added interest to the piece. Dana, father of mineralogy, describes them as "tabular appearing twins." Thanks to the quality and quantity of twinned crystals, we now have a much more managable name.

One of my summer interns was one of a set of identical twins, with his "better half" stationed in Japan. He gifted his brother with a Japanese Law Twin, which I think is wonderfully geeky!
